Davis Northern and Nancy Holston Northern

I am seeking information about Davis Northern and Nancy Holston Northern.About 1931, Nancy applied for a Civil War Widow's Pension in Grainger County, Tennessee.

It doesn't contain a lot of personal information, as they usually do.

Here is my theory.I believe that Nancy was born Holston Hounshell, daughter of Robert A. Hounshell and Elizabeth Tarter.Robert's mother was Nancy Holston who married William Hounshell.I believe Nancy Northern was really Nancy Holston Hounshell and that she married Davis Northern on July 10, 1886 in Hawkins County, Tennessee.Davis Northern died December 17, 1917. Pursuant to further research, I learned that they had a son named David H. Northern.
